Every law enforcement agency will tell you that the supervision core is the backbone of the department. Efficiency, effectiveness, and integrity of any organization relies in the hands of supervisors. They are the professionals who make sure the shift is running smoothly and assessing every aspect of the service being provided to the community. The Shafter Police Department has a great staff who we believe are among the best in the business. We’d like to use this forum to introduce them to you, their professional backgrounds, and their specialties.

Animal Control Manager Nick Riddick
Animal Control Manager Nick Riddick was born and raised in Fresno, California. He attended the University of California, Riverside leaving for a supervisor position at a Fortune 500 Company.
Life would lead him back to the beautiful San Joaquin Valley, however, and to the City of Shafter which he now calls home. Nick has been a resident in Kern County for nine years, where he found his calling in the Animal Control field.
In November of 2009, he accepted a position as an Animal Control Officer for the County of Kern. He was selected as the Lead Officer in the newly revamped Public Education and Enforcement Team Program, or PEET. This program consisted of public outreach to promote the importance of licensing and vaccinating pets as well as responsible pet ownership.
With a successful tenure as the “PEET” Officer, Nick ventured into field services which entailed responding to a variety of animal related issues. It was not until he began responding to reports of Animal Cruelty and seeing firsthand the kinds of terror that can be inflicted upon animals that he realized he had a golden opportunity to effect change, hold people accountable for their actions, and save lives. He carries this creed to whatever situation life presents and is steadfast in upholding these values for the citizens of this community.
In 2013, Nick accepted the position of Animal Control Manager for the City of Shafter, bringing with him the experience and understanding of community involvement and participation. This has resulted in an increase adoption levels and rescue live release rates of animals, while steadily maintaining increased animal intake numbers and calls for service.
Nick has a team of professionals and volunteers who are vigilant in impounding stray and marauding animals, but also dedicated to work toward lowering the annual euthanasia rate. This multi-pronged approach is accomplished partially with increased live release rates, carefully vetted rescue partners, and a thriving volunteer program.
In 2015, Officer Riddick was awarded the Officer of Year and continues to strive for the dedication to service the citizens of our community deserve.
